I agree, I've used IRC for more that I should have, I use Skype for quite some time now, not ten years yet, and is far more advanced and conformable than Twitter/Facebook, Google Hangouts are getting better, but still not good enough for daily basis use.
--Edit:
I recently started to use ICQ, due it's really popular in Russian and Eastern European countries, it has come a long way from what it was at the beginning.
